Lithium niobate particles with a tunable diameter and porosity for optical second harmonic generation.

ABSTRACT: Uniform, porous particles of lithium niobate (LiNbO₃) can be used as contrast agents in bioimaging, drug delivery carriers, nonlinear optical emitters, biosensors, photocatalysts and electrode materials in lithium-ion batteries. In this article, we introduce a hydrothermal method to prepare uniform, mesoporous LiNbO₃ particles with a tunable diameter and porosity. These properties are each tuned by adjusting the reaction times of the hydrothermal process. This approach forms mesoporous LiNbO₃ particles without the addition of organic additives (e.g., surfactants) or hard templates (e.g., silica). Formation of these LiNbO₃ particles proceeds through an aqueous sol-gel reaction in which niobium hydroxide species are generated in si
